Within the Datamath Calculator Museum you'll notice a lot of credit card sized calculators like the TI-1754, TI-1780, TI-1786, TI-307, Canon LC-7, or Toshiba LC-851. All these calculators have two dimensions common: The length and the width. But we never talked about the third dimension, the height or thickness of the calculators.
